Stefano Garzarella 512da21101 linux-aio: add dev_max_batch parameter to laio_co_submit() 
This new parameter can be used by block devices to limit the
Linux AIO batch size more than the limit set by the AIO context.

file-posix backend supports this, passing its `aio-max-batch` option
previously added.

Add an helper function to calculate the maximum batch size.
